Description

EXAMPLE A

Self-Reversible Reverse Latex of an NaATBS/HEA Copolymer Crosslinked with MBA

(1) Aqueous Phase Preparation

(2) The following are placed in a beaker, with stirring:

(3) 672.5 g of a commercial solution at 55% by mass of the sodium salt of 2-methyl-2-[(1-oxo-2-propenyl)amino]-1-propanesulfonic acid (NaATBS), 20.8 g of 2-hydroxyethyl acrylate (HEA), 0.152 g of methylenebis(acrylamide) (MBA), 0.45 g of a commercial solution at 40% by mass of sodium diethylenetriaminepentaacetate.
The pH is adjusted to 4 with 2-methyl-2-[(1-oxo-2-propenyl)amino]-1-propanesulfonic acid and the aqueous phase is then made up to 700 g with water.
Preparation of the Organic Phase
The following are mixed together by simple stirring in a beaker: 220 g of Isopar M (C13/C14 isoparaffin), 20 g of a solution of stearyl methacrylate/N,N-dimethylacrylamide/behenyl methacrylate ethoxylated with 25 mol as a 46% solution in Isopar M, 0.15 g of AIBN (azobis(isobutyronitrile)).

(4) The aqueous phase is then poured into the oil phase with stirring and the mixture is emulsified, while maintaining the beaker in an ice bath, using an Ultra-Turrax turbomixer until a viscosity of about 4600 mPa.Math.s is obtained (Brookfield RVT M4, V20). The emulsion is then placed in the polymerization reactor. Sparging with nitrogen is performed for about 45 minutes while cooling the reactor to about 8 C. 10 cm.sup.3 of a solution containing 0.17% (mass/volume) of cumene hydroperoxide in Isopar M are then added, followed by an aqueous solution of sodium metabisulfite at 0.27% (mass/mass) in water at a rate of 0.5 cm.sup.3/minute. The introduction is stopped at the end of the exothermicity. A stable self-reversible reverse latex, referred to hereinbelow as the self-reversible reverse latex (1), is obtained at the end of polymerization.

(5) Evaluation of the Properties

(6) Viscosity of the self-reversible reverse latex (Brookfield RVT, M3, 20 rpm): =1.800 mPa.Math.s

(7) Viscosity of the self-reversible reverse latex mixed to 2% by mass in water (Brookfield RVT, spindle 5; 5 rpm): =158 000 mPa.Math.s

(8) This viscosity is obtained without addition of a surfactant. Furthermore, the rate of inversion is about 2 minutes and thus similar to that obtained for standard reverse lattices.

EXAMPLE B

Concentrated Self-Reversible Reverse Latex of an NaATBS/HEA Copolymer Crosslinked with MBA

(9) Preparation of the Aqueous Phase

(10) The same aqueous phase as that of Example A, with the exception of the amount of methylenebis(acrylamide) which is reduced to 0.028 g, is prepared.

(11) Preparation of the Organic Phase

(12) The following are mixed together by simple stirring in a beaker:

(13) 100 g of Isopar H 200 g of C8-C10 triglyceride 25 g of a solution at 46% in Isopar M of stearyl methacrylate/N,N-dimethylacrylamide/behenyl methacrylate ethoxylated with 25 mol in solution 0.15 g of AIBN (azobis(isobutyronitrile)).

(14) The aqueous phase is poured into the oil phase with stirring and the mixture is emulsified, while maintaining the beaker in an ice bath, using an Ultra-Turrax turbomixer until a viscosity value of about (3000 mPa.Math.s) is obtained (Brookfield RVT M4, V20). The emulsion is then placed in the polymerization reactor. Sparging with nitrogen is performed for about 45 minutes while cooling the reactor to about 8 C. 10 cm.sup.3 of a solution at 0.17% (mass/volume) of cumene hydroperoxide in C8-C10 triglyceride are then added, followed by an aqueous solution of sodium metabisulfite at 0.27% (mass/mass) in water at a rate of 0.5 cm.sup.3/minute. The introduction is stopped at the end of the exothermicity. Next, one hour after the end of the polymerization, the reactor is placed under partial vacuum to a value of about 1710.sup.3 Pa and the temperature is adjusted to 80 C. so as to remove the Isopar H and the water by evaporation. After cooling, a concentrated self-reversible reverse latex containing about 65% by mass of anionic polyelectrolyte, referred to hereinbelow as the self-reversible reverse latex (2), is obtained. This latex is stable with respect to sedimentation and reverses spontaneously in water.

(15) Evaluation of the Properties

(16) Viscosity of the self-reversible reverse latex (Brookfield RVT, M3, 20 rpm): =3.800 mPa.Math.s.

(17) Viscosity of the self-reversible reverse latex at 2% in water (Brookfield RVT, M5; 5 rpm): =63 600 mPa.Math.s.

(18) This viscosity is obtained without the addition of surfactant. Furthermore, the rate of inversion is about 4 minutes and thus similar to that obtained for concentrated reverse lattices.

(19) Viscosity of the self-reversible reverse latex at 2% in water+0.1% sodium chloride (Brookfield RVT, spindle 5; 5 rpm):

(20) =31 000 mPa.Math.s.
